BURNER.

Application iled April 11, 1925. Serial No. 22,384.

To all whom it may concern:

Be it known that I, BENJAMIN F. VALDRON, a citizen of the United States,residing at Duncan, in the county of Stephens and State of Oklahoma,have invented a new and useful Burner, of which the following is aspecification.

The device which constitutes the subject matter of this application is aburner adapted to be used in boiler furnaces, or elsewhere, and the`invention aims to provide novel adjusting means, to supply novel meanswhereby a proper mixture will be secured, and to supply means wherebythe mixture can be spread or dispersed more or less, at the will of anoperator.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains, it being understood that a mechanic, working within thescope of what is claimed, may make changes, without departing` from thespirit of the invention.

In the drawings Figure 1 shows in longitudinal section, a deviceconstructed in accordance with the invention, parts being in elevation;Figures 2, 3 and 4 are sections taken respectively on the lines 2 2, 3 3and 4 4 of Figure 1.

The device forming' the subject matter of this application comprises abody, which as a whole, is marked by the numeral 1, the body including acasing 2 provided with a partition 8 defining a fuel chamber and apressure chamber 5. Fuel, in the form of gas or oil, is supplied to thechamber 4 through a pipe 6, a pipe 7 serving to supply steam to thepressure chamber 5. The body 1 includes, further, a nozzle 8, thereduced end 9 of which is threaded into the casing 2, said end forming ashoulder 10 in the nozzle 8. The nozzle 8 has a large bore 11coniinunicating with a smaller bore 12, and at the rear end of the bore12 there is a seat 14, the nozzle, briefly stated, being connected witht-he casing 2 and communicating with the 'fuel chamber 4. In theshoulder 10 of the nozzle 8 there are any desired number of inwardlyinclined air inlet ports 15.

The casing 2 has a reduced neck 16 carrying a gland 17. In the gland 17and in the neck 16, a tubular valve 18 is slidable, the forward end 19of the valve being so shaped that it will cooperate with the seat 14.The valve 18 slides in a gland 2O carried by the partition 3. The valve18 has anydesired number of openings 21 communicating with the pressurechamber 5. Thevalve is supplied in its forward end with any desirednumber of outlet duets 22 discharging through the seat 14. A carrier 23,in the form of a rod,- is slidably supported in a way which will bepointed out hereinafter, a head 24 being mounted on the forward end ofthe carrier 23 and being provided with a plurality of spiral ribs 25fitting closely but slidably in the nozzle 8, at the forward endthereof. An auxiliary fuel supply conduit 26 is assembled with the part9 of the nozzle 8 and opens into the bore 12 to the rear of the airinlet ports 15. A valve'27, under the control of an operator, isinterposed in the auxiliary fuel supply pipe 26.

The operation of the device as thus far described, is as follows y Fuelenters the chamber 4 through the pipe 6 and flows through the seat 14and through the bores 12 and 11 of the nozzle 8, under the governance ofthe valve 18, which may be moved endwise, toward and away from the seat14. Steam enters the charnber 5 through the pipe 7 and passes into thehollow valve 18 through the openings 21, the steam being discharged withgreat force through the ducts 22, and carrying the fuel forwardly in thenozzle 8, air being drawn in through the ports 15. The mixture, movingout of the end of the nozzle 8, will be given a whirling motion by theribs 25 of the head 24, and the amount that the mixture is scattered,dispersed and broken up, will depend upon the position of the head 24with respect to the end of the nozzle 8, longitudinal movement beingimparted to the head by way of the carrier rod 23. If, 'for any reason,an auxiliary supply of fuel is desired, such a supply may be obtained byopening, more or less, the valve 27 in the pipe 26.

It. remains to discuss the means whereby longitudinal movement isimparted to the valve 18 and to the carrier rod 28. ln this connection,it is to be observed that a U- shaped support 28 is provided, the sameincluding a main bar 29 provided at one end with an arm 30 terminatingin a ring 31 surrounding the neck 16 of the casing 2, and held in placeby a nut 82. At its rear end, the bar 29 carries a bearing 33 locatedabout parallel to the arm 30.' Intermediate its ends, the bar 29 carriesa bearing 34, similar to the bearing 33. A bearing arm 35 projects fromthe bar 29 and is located between the bearings 33 and 34. A bearing36 isthreaded at one'end -into the valve 18, the opposite end of the bearingcarrying a gland 37. rIhe carrier rod 23 slides in'the bearing 36, thegland 3"? and in the armi35. For convenience in describing the inventionconcisely, the bearing 36 maybe considered to bea part of the valve 13.The member 36 has ears 33 between which lOperates an eccentric 39forming part of a foot 40 on a shaft 4l journaled in thel bearing 34,the foot 40 being held against the end of the bearing 34 by acompressionspring 42, one end of which is received in a seat 43 on thebar 29, the other end ofthe spring engaging an abutment 44 on the shaft41, the shaft being supplied witha hand wheel-45,y or with any other'suitable means whereby it may be rotated. A glance yat Figure l willshow that when the shaft 4l ,is rotated by means of the hand wheel 45,theeccentric 39, cooperating with the ears 3301i the member 36, willimpart longitudinal movement to the valve 13, as and for the purposehereinbefore set forth. n

`.A bracket- 46 is adjustable on the carrier rod 23,longitudinally,thereof, andis held in adjusted positions by a lset screw47,r the bracket having ears 43, corresponding to the elements 33. Thebearing 33- carries a mechanism 49 which, coacting with the ears 48,imparts longitudinal movement to the carrier rod 23. The mechanismindicated at 49 need not bev describedin detail, because it isa'substantial duplicate ofthe structure beginning with the eccentric 39and ending with' the hand wheel 45.

I claim y, V j

l. In a burner of the class described, a body comprisingza casingprovided with a partition defining a fuel chamber and apressurecliamber, and a nozzle connected to admission openingcommunicating with the pressure chamber-,and having an outlet ductdischarging through the. seat, acarrier slidable in the valve andintheinozzle, a regulatingr head on the carrier and' operating in thenozzle, means for yoperating ther Walve, and means for'operating'thecarrier.

2. A device of'the'class described, constructed as set forth in claim l,and further characterized by the `fact-:that-the nozzle is suppliedintermediate its end with anair inlet port, andagovernedfuel'supplyidischarging into the nozzle to the rear of the port. i

3. A device of theclass described, vconstructed asset forth in claim l,and further characterized by the'factthat oney of .the last-specifiedmeans comprises a support mounted-onthe body, a shaftjournaled in thesupport, and an eccentric on the' shaft.

4. A device of the class rdesc1iloed',*con structed as set forth inclaim'l, and further characterized by the fact thatboth of thelast-specied means comprise a support carried by the body, shafts-journal'edin the support, eccentrics on the shafts, and memberswherewith the eccentrics cooperate, said members being mounted,respectively, on ythe carrier and on the valvefone'of saidmembersbeingadjustable longitudinally ofthe part whcreon it is mounted,'andmeans for holding the said member in adjusted positions.

In testimony that I claim the foregoing as my own, I have hereto afIiXedmy signature. i
